Turning to a question about the rotating Zack replacements in the lab, Hanson said the storyline was intended to help develop the lab-based B story in the episodes, and he sees it as so successful, the writers now intend to keep the interns for a while, instead of replacing Zack quickly. And that may not be a bad thing for Zack fans, as Hanson confirmed there is more yet to come about that character.

With psychiatrist Sweets knowing that there is more to Zack’s story, he faces a dilemma on how to proceed. Hanson said he has been looking into bringing back Gordon Gordon (English actor Stephen Fry) as the person to help Sweets sort things out, though Fry’s availability has not been confirmed.

I'm excited about the Stephen Fry (possible) return, but do wonder about his availability. If you follow him at all, it's clear he's tied up for quite some time as he travels the world filming a series on endangered species, most recently in Africa.
